mvk, thanks for the heads up i also am leery about this one window fearing that if i attempt to activate it ( down \wards) it will not go up again, on the other hand how do u find out if it will work or not if u don't take the risk! as i said it would not move
from the closed position for 6 years and all of a sudden it works both ways - i felt bold enuff to try it as it was a warm/dry day -it must be gremlins ?!
